## What it is
nearcore is the reference client implementation of the NEAR Protocol, a sharded proof-of-stake blockchain written in Rust. It runs full nodes and validators that execute smart contracts compiled to WebAssembly and maintain the NEAR network's state.

## Use cases
- run a NEAR Protocol node
- operate a validator for the NEAR blockchain
- sync a full archive node for NEAR
- develop and test NEAR protocol changes
- host an RPC endpoint for NEAR dApps
- execute WebAssembly smart contracts on NEAR

## When to choose
- you need to run or validate on the NEAR network
- you're contributing to NEAR Protocol core development
- you need a self-hosted NEAR RPC node instead of third-party providers
- you're building infrastructure or tooling that requires direct node access

## When to avoid
- you just want to write smart contracts (use near-sdk-rs or near-sdk-js instead)
- you want to interact with NEAR from a frontend (use near-api-js)
- you're building on a different blockchain
- you need a lightweight wallet rather than a full node

## Facets
- artifact type: application
